Neopentyl Glycol (NPG)

CAS 126-30-7

Neopentyl Glycol (NPG) is a branched diol used as a core intermediate for polyester resins, powder coatings, polyurethane systems, and specialty chemical synthesis. The product page uses high-confidence supplier data as a verified draft basis while final grade, form, and packaging remain subject to JYT quotation confirmation.

  • Neopentyl structure improves hydrolysis resistance in polyester systems
  • Widely used in powder coatings, saturated polyesters, and unsaturated polyester resins
  • Suitable building block for polyurethane foam and elastomer applications
  • Supports formulation needs for plasticizers, stabilizers, and industrial intermediates
